Results of international comparative interlaboratory tests on defining contents of nitrogen oxides (NO, NOx) in gaseous phase of aerosol of heated tobacco products are presented in the article. The objects of study were samples of heated tobacco intended for use with electric tobacco heating systems of the IQOS, Glo and Ploom brands. The determination of nitrogen oxides in the gas phase of aerosol from heated tobacco products was carried out using a technique developed in the laboratory of chemistry and quality control of the Federal State Budget Scientific Research Institute “All Russian research institute of tobacco, makhorka and tobacco products”. The aim of interlaboratory comparative tests is calculation of intra- and interlaboratory variability (repeatability and reproducibility). Mandel h and k statistics were utilized for statistical compatibility analysis. Analysis of interlaboratory compatibility was carried by z - index, statistical identifying of outliers was carried by Cochran’s and Grubbs’ criteria. Also, repeatability and reproducibility were calculated. Statistical analysis of interlaboratory comparative tests results proved high level of validity of obtained data. Establishing metrological characteristics is a key aspect of ensuring the reliability and applicability of the methodology. Interlaboratory comparative tests for nitrogen oxides defining are the first time carried in Russia and are actual for innovative products from heated tobacco.
